Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED matrix displays are used to fit limited space in automated transportation systems, then the display can be customized to unique space constraints, but the resolution and color quality are insufficient and high-resolution full-color images cannot be displayed
Solution Approach 1:
The display system is segmented into multiple individual LED modules, each with its own control circuitry. This allows the display to be divided into manageable units that can be arranged in various configurations to fit different space constraints while maintaining high resolution through precise control of each segment.
Solution Approach 2:
Multiple LED modules are merged into a unified display system with integrated control. The modules work together as a single high-resolution display unit, combining the advantages of LED flexibility with high-quality image and video capabilities that individual LED matrices cannot achieve alone.
2Manufacturing precision
If standard LCD panels are strung together in a row to replace LED matrix displays, then high-resolution full-color images and video capabilities are achieved, but dead space between panels is created and the system becomes more complicated
Solution Approach 1:
Multiple LCD panels are merged into a single unified display system with continuous pixel arrays across panel boundaries. The control system treats the entire assembly as one logical display device, eliminating the need for separate control of each panel and removing dead spaces through precise edge-to-edge positioning.
Solution Approach 2:
An intermediary control system and mounting structure are introduced that mediate between individual LCD panels and the final unified display output. This intermediary layer handles the complexity of panel integration, pixel alignment, and signal routing, presenting a simple unified interface to the user while managing the complexity internally.
3Area of stationary object
If multiple LCD panels are placed side by side to achieve ultra-wide aspect ratio, then the display area is increased, but visual separations are created due to larger spacing between edge pixels
Solution Approach 1:
The edge regions of adjacent LCD panels are given special local quality treatment with adjusted pixel characteristics. The display system varies the pixel density and positioning locally at panel boundaries to ensure seamless visual continuity, creating an optical illusion of uniform pixel spacing across the entire ultra-wide display area.
Solution Approach 2:
The physical parameters of the display system are changed by using flexible printing technology to create displays with non-standard pixel geometries and variable pixel pitch. This allows the pixel spacing to be optimized locally at panel edges to eliminate visual separations while maintaining high resolution across the entire ultra-wide display area.
